I had an adopted daughter that was constantly jealous of a new baby that never existed (plus many other negative traits - subsequently I actually used a backup save game file to remove her hehe!)

Speaking as an only child (so I don’t know) I think the jealousy thing is a bit unrealistic and so shouldn’t be part of this game....others may disagree however a little child acting-out out of ‘jealousy’ ?

It’s a little bit too much, and quite hard to deal with as an onlooker...
